plate C;,and an outer flange p to fit over the edge of the wall whichsurrounds the opening q'. The opening or chamber p8 is threaded,

as shown at p7, to receive the threaded end of` a pipe E.

D is a damper which rests upon the upper surface of the top-plate B. Ithas a central annular projection n on its `under side to fit the'openingp8, and may beturned to regulate the sizes of the draft-openings p.

The consti-notion shown and described is designed lmore especially forvaporizing and burning hydrocarbon oil, which is fed through the pipe E.In practice the pipe E extends beyond one edge of the stove to whichthe' burner is applied and iS there connected, preferably, by means of aflexible rubber .hose with an oil lsupply tank, placed at any safe andconvenient distance from the stove at an elevation with relation to theburner. In` practice I prefer to provide a small quantity-vv When theoilv is turned on at. the pipe F it flows into the chamber p3 anelthence through the funnel#V of asbestos Y in the recess t.

shaped opening p4 to the gutter s at the shallow part thereof. Thegradually deepening shapeof the gutter causes the oil to fiowarouud thecircle to the point Initially the oil is allowed to fill the gutter andoverfiow through the opening 'r' and saturate the asbestosY.`

A match is then applied to the asbestos and theoil ignited. lhe naturaltendency of the draft is toward the outlet flue of the stove.Consequently, air to supply combustion, enters through thedraft-openings p and the products of combustion pass over the wall t2 tothe outlets t2 and there escape into the Stove, As the products ofcombustion pass over the wall t2- they strike the lower V-shaped'surface of the plate B and soon heat the gutterportion of the latter toa high temperature. As a consequence the oil entering the gutter andflowing around the same is quickly vaporzed and caused to escape in theform of vapor and gas through the'annular burner opening r'. Th us whileair enters the chamber formed by the gutter s it; covering plate C itis' immediately vaporized and more or less gasified and fills thechamber throughout and escapes equally through all parts of theburneropening'r. Consequently,asheet of flame of equal size andintensity is directed radially 4inwardly from the burner-opening and iscarried downward under the flange s3, over the wall t2 and under thegutter s' to theoutlets t3, whence the products of combustion movebackward in the stove, filling the flue-chambers or passages and heatingall parts of the stove in the same way as when coal or wood are employedas the fuel. The size of the flame may be readily regulated byregulating the supply of oil flowing through the pipe E, a suitablevalve,'of course, being provided for that purpose. The ingress of air tosupply combustion may be easily and effectively regnlated by means ofthe damper D', so that the heat may be easily and eiectively controlledat all times.

IE it is desired to employ hydrocarbon gas, either natural ormanufactured, instead of oil 7o as the fuel, the pipe E is connectedwith the gas supply, by means of a rubber hose or otherwise,and in thepipeE is interposed an air inlet valve, which may be on the principle ofthe Bunsen burner, to admit a desired quantty of air with, the gas tothechamber s. The gas is heated in the chamber s' to a high temperaturebefore it escapes from the burneropening 1*', and its combustion andheating qualities thus greatly/augmented.

The partsA B C D and D are not secured together and may therefore bereadily sepa-v rated for purposes of cleaning and as readily replaced.

My improvement is adapted for cooking stoves and ranges generally, and,as before stated, fits into a stove-hole X of the stove or range-top Z.The vaporizing of the oil before it escapes'from the burneropeningrr',and the down draft which prevents the escape of lfumes through the topof the stove, makes the burner odorless; and itis, furthermore,perfectly safe,and economical. T-he spacing lugs p prevent a vessel,imposed upon the burner, from interfering with the draft.`

While I prefer to construct my improvements in every way as shown anddescribed,

they may be modified in the matter of details of'construction withoutdeparting from the spirit of my invention as defined by' the rco claims..l

What I claim as new, and desire to secure hyp/Letters Patent, is-

1. 4In a hydrocarbon burner, the combina- V tion of a dish-shaped casinghaving acircumro5 ferential flange at its upper side to lita stovehole,upper and lower annular burner plates fitting into said casing andaffording an'annular vaporizing chamber above the base of the casing,and provided with a narrow continuous inner-circumferentialburner-opening, a top plate upon the casing having an oil supply passageleading to said burner, and a central draft opening, a damper at thedraft opening, and outlet openings in the casing about the lower burnerplate, whereby products of combustion pass from the burner openingaround the vaporizing chamber to heat the latter, substantially asdescribed.
